안녕하세요

It seems return type of the method findByid(Long id) should be Optional(Member).

직접 만든 라이브러리의 경우 어떻게 배포 되는건가요?

We normally never include any built files - jar, war - in the source code repository like GitHub. Instead, we have a separate repository (e.g. Nexus) where the jar file is uploaded, so projects can just declare the dependency (e.g. pom.xml for maven) to download it.

MemberService에 @Transactional 붙이는 이유

Though it is just a guess, in the pure jdbc example you might explicitly open/close transaction in the code. On JPA, same functionality is controlled by the Transactional annotation.

안녕하세요

API can be used by any agent - web, mobile or other systems. Reason it uses restApi is to simply return data only, as opposed to normal controller returns html element.

강사님 질문 있습니다!

In the first line, you can only access methods/variables defined in the Reportable interface. In the second line, you can access methods/variables defined in the FactoryCam class which could be larger than Reportable.

세션은 브라우저가 종료되면 sessionid를 제거한대요

When browser closes, the session id set in the ‘browser cookie’ is removed. It does not mean that session in the server is removed. However, after the certain amount of time, the session in the server will be also deleted as it wont be called anymore and hit the session max lifetime.

상품 주문 시 주문 내역에 값이 들어가 있지 않습니다

Though I need more context to oroperly tackle this question, it is highly likely that orderSearch condition is set in a way query does not return the orders. Please check what is set and what is supposed to set in the orderSearch parameter.
